Sie können auch in Form ihrer technischen Gemische eingesetzt werden, die in der Regel mehrere Verbindungen der genannten Art enthalten (Homologengemische).The compounds corresponding to components B) to E) are commercially available. They can also be used in the form of their technical mixtures, which generally contain several compounds of the type mentioned (homolog mixtures).
Die erfindungsgemäßen wäßrigen Dispersionen können neben den Komponenten A) bis F) auch noch weitere zweckmäßige Komponenten enthalten. So kann die Dispersion ein in Wasser unlösliches oder schwer lösliches,aliphatisches Keton mit einem Siedepunkt von über 100 °C enthalten; Beispiele dafür sind aliphatische Ketone mit 5 bis 8 C-Atomen wie Diethylketon, Methylpropylketon, Methylisobutylketon und ähnliche.

These ketones are used in an amount of preferably 5 to 10% by weight, percentages by weight based on the aqueous dispersion, and can replace a corresponding part of component D).
Die Herstellung der erfindungsgemäßen wäßrigen Dispersionen erfolgt durch Zusammenmischen der einzelnen Komponenten. Dabei wird vorzugsweise so vorgegangen, daß die Komponenten A), B), C), D) und E) in Wasser (Komponente F) unter Zufuhr einer relativ großen Energiemenge dispergiert werden. Die Mengenverhältnisse für die Komponenten werden dabei so gewählt, daß nach der Dispergierung die angegebene Zusammensetzung für die Dispersion erreicht wird. Es hat sich als vorteilhaft erwiesen, daß die Komponente A) (das ist die erfindungsgemäße Verbindung, der Wirkstoff) zumindest in einem Teil der zur Anwendung kommenden Menge an Komponente D) und E) vordispergiert und in dieser Form eingesetzt wird. Es hat sich ferner als vorteilhaft erwiesen, die Herstellung der wäßrigen Dispersion in zwei Teilschritte aufzuteilen und zuerst eine Vordispergierung und anschließend eine Feindispergierung vorzunehmen. Die Vordispergierung wird zweckmäßigerweise durch Anwendung hoher Scherkräfte vorgenommen, wie sie bei Verwendung eines schnell laufenden Rührers, beispielsweise eines Rührers (Dispergiermaschine) vom Typ Ultraturrax vorliegen, und die dabei erhaltene Vordispersion (Rohdispersion) wird anschließend zweckmäßigerweise einer Ultraschallbehandlung oder einer Behandlung in einem Hochdruckhomogenisator unterzogen. Nach Beendigung dieser Behandlung liegt die Teilchengröße in der Dispersion zu über 80 %, vorzugsweise zu über 95 %, bei oder unter 1 um (Feindispersion).The aqueous dispersions according to the invention are prepared by mixing the individual components together. The procedure is preferably such that components A), B), C), D) and E) are dispersed in water (component F) while supplying a relatively large amount of energy. The proportions for the Components are chosen so that the specified composition for the dispersion is achieved after dispersion. It has proven to be advantageous that component A) (that is the compound according to the invention, the active ingredient) is predispersed at least in part of the amount of component D) and E) used and is used in this form. It has also proven to be advantageous to divide the production of the aqueous dispersion into two substeps and to first carry out a predispersion and then a fine dispersion. The predispersion is expediently carried out by using high shear forces, such as are present when using a high-speed stirrer, for example a stirrer (dispersing machine) of the Ultraturrax type, and the predispersion (crude dispersion) obtained is then expediently subjected to an ultrasound treatment or a treatment in a high-pressure homogenizer . After this treatment has ended, the particle size in the dispersion is more than 80%, preferably more than 95%, at or below 1 µm (fine dispersion).
Gegenstand der Erfindung ist schließlich die Verwendung der beschriebenen wäßrigen Dispersionen. Sie werden erfindungsgemäß zur Behandlung von Textilien, Leder und Pelz und von unlackiertem Holz (vorzugsweise unlackierten Möbeln) eingesetzt. Sie verleihen diesen Artikeln, insb. Textilien, Leder und Pelz, hervorragende Hydrophob- und Oleophobausrüstung. Bei der Anwendung auf Textilien können die wäßrigen Dispersionen in der Form eingesetzt werden, in der sie bei der Herstellung anfallen. Normalerweise wird man sie jedoch mit Wasser auf einen Feststoffgehalt von 1 bis 10 Gew.-%, vorzugsweise 1,5 bis 5 Gew.-% (Gewichtsprozente bezogen auf die wäßrige Dispersion), einstellen und in dieser verdünnteren Form einsetzen.The invention finally relates to the use of the aqueous dispersions described. They are used according to the invention for the treatment of textiles, leather and fur and of unpainted wood (preferably unpainted furniture). They give these articles, especially textiles, leather and fur, excellent hydrophobic and oleophobic finishing. When used on textiles, the aqueous dispersions can be used in the form in which they are produced. Normally, however, they will be adjusted to a solids content of 1 to 10% by weight, preferably 1.5 to 5% by weight (percentages by weight based on the aqueous dispersion), with water and used in this more dilute form.
Zur Ausrüstung vorbroschierter Leder und Pelze können die wäßrigen Dispersionen im Falle der Badanwendung direkt und ohne weitere Vorverdünnung in der Form eingesetzt werden, in der sie bei der Herstellung anfallen. Für die Ausrüstung trockener Leder und Pelze nach dem Spritzauftragsverfahren wird man sie jedoch normalerweise vorab mit Wasser auf einen Feststoffgehalt von 1 bis 10 Gew.-%, vorzugsweise 4 bis 8 Gew.-% (Gewichtsprozente bezogen auf die wäßrige Dispersion), einstellen und in dieser verdünnteren Form einsetzen.In the case of bath use, the aqueous dispersions can be used directly and without further predilution in the form in which they are produced to finish pre-broached leather and furs. For the finishing of dry leather and furs by the spray application process, however, they will normally be adjusted beforehand with water to a solids content of 1 to 10% by weight, preferably 4 to 8% by weight (percentages by weight based on the aqueous dispersion), and in use this thinner form.
Die erfindungsgemäßen wäßrigen Dispersionen erfüllen alle Forderungen der Praxis und zeigen insbesondere eine ausgezeichnete Langzeit-Stabilität bei Temperaturen von -20 bis +40 °C. Sie gefrieren zwar bei Minustemperaturen, die Dispersion bleibt aber nach dem Auftauen erhalten. Neben der hervorragenden Oleophobierung und Hydrophobierung wird eine generelle Schmutzabweisung und auch eine Leitfähigkeitsverbesserung erreicht. Die beschriebenen wäßrigen Dispersionen können sowohl allein für die in Rede stehenden Ausrüstungen eingesetzt werden, als auch in Kombination mit beispielsweise üblichen Spinnpräparationen bzw. Lederfettungsmitteln oder anderen Ausrüstungsmitteln wie Antistatika, optischen Aufhellern, Textilharzen auf der Basis Glyoxal oder dessen Derivaten, Weichmachern und Dispersionen von Polyvinylalkohol und Ethylen-Vinylacetat-Polymeren, mineralischen und synthetischen Gerbstoffen und Harz- und Polymergerbstoffen.The aqueous dispersions according to the invention meet all practical requirements and in particular show excellent long-term stability at temperatures from -20 to +40 ° C. Although they freeze at sub-zero temperatures, the dispersion remains after thawing. In addition to the excellent oleophobization and hydrophobization, a general dirt repellency and also an improvement in conductivity are achieved. The aqueous dispersions described can be used both for the equipment in question, and in combination with, for example, conventional spin finishes or leather greasing agents or other finishing agents such as antistatic agents, optical brighteners, textile resins based on glyoxal or its derivatives, plasticizers and dispersions of polyvinyl alcohol and ethylene vinyl acetate polymers, mineral and synthetic tanning agents, and resin and polymer tanning agents.
Bezüglich der Art und Form des zur Behandlung eingesetzten Textilmaterials gilt das Obengesagte. Das Textilmaterial kann also natürlicher oder synthetischer Natur sein. Die wäßrigen Dispersionen eignen sich besonders vorteilhaft bei einem Textilmaterial aus Polyamid, Polyester und/oder Polyacrylnitril, insbesondere aus Polyamid. Das Textilmaterial kann in beliebiger Form vorliegen; in der Regel wird es sich um Fäden, Fasern, Gewebe oder Teppiche handeln. Die Behandlung von Textilmaterial mit den erfindungsgemäßen wäßrigen Dispersionen wird nach üblichen Methoden durchgeführt, so zum Beispiel durch Sprühen, Tauchen, Pflatschen, Foulardieren und dergleichen. Die Auftragsmenge wird so gewählt, daß die Menge an Fluor des Wirkstoffs (erfindungsgemäße Verbindung) auf dem Textilmaterial 0,02 bis 1 Gew.-% beträgt, vorzugsweise 0,04 bis 0,4 Gew.-%, Gewichtsprozente bezogen auf das behandelte Textilmaterial. Nach dem Aufbringen auf das zu behandelnde Textilmaterial erfolgt eine Trocknung bei Temperaturen bis ca. 120 °C, zum Beispiel bei 100 bis 120 °C, und anschließend wird eine Wärmebehandlung bei Temperaturen von ca. 130 bis 190 °C, vorzugsweise 140 bis 180 °C, durchgeführt, die normalerweise etwa 30 Sekunden bis etwa 4 Minuten dauert (sofern Trocknung und Wärmebehandlung im Rahmen der Herstellung des Textilmaterials nicht ohnehin vorgenommen werden).The above applies to the type and shape of the textile material used for the treatment. The textile material can therefore be natural or synthetic in nature. The aqueous dispersions are particularly advantageous in the case of a textile material made from polyamide, polyester and / or polyacrylonitrile, in particular from polyamide. The textile material can be in any form; usually it will be threads, fibers, fabrics or carpets. The treatment of textile material with the aqueous dispersions according to the invention is carried out by customary methods, for example by spraying, dipping, splashing, padding and the like. The amount applied is chosen so that the amount of fluorine of the active ingredient (compound according to the invention) on the textile material is 0.02 to 1% by weight, preferably 0.04 to 0.4% by weight, percentages by weight based on the treated textile material . After application to the textile material to be treated, drying is carried out at temperatures up to approximately 120 ° C., for example at 100 to 120 ° C., and then heat treatment is carried out at temperatures of approximately 130 to 190 ° C., preferably 140 to 180 ° C, which normally takes about 30 seconds to about 4 minutes (unless drying and heat treatment are not carried out in the course of the manufacture of the textile material anyway).
Bezüglich der Art und Herkunft der auszurüstenden Leder und Pelze gibt es, wie oben bereits erwähnt wurde, keine Beschränkungen. Sie sollten vor der Behandlung mit der wäßrigen Dispersion nach Möglichkeit jedoch nicht mit stark wasserabstoßenden Mitteln, wie zum Beispiel einer Polyurethanzurichtung abgedeckt sein, um eine sichere und gleichmäßige Penetration zu erzielen.As already mentioned above, there are no restrictions on the type and origin of the leather and fur to be finished. Before treatment with the aqueous dispersion, however, if possible, they should not be covered with highly water-repellent agents, such as a polyurethane coating, in order to achieve a safe and uniform penetration.
Die Behandlung der Leder und Pelze mit den erfindungsgemäßen wäßrigen Dispersionen wird nach den üblichen Methoden durchgeführt, so zum Beispiel im Bad, durch Tauchen, Aufbürsten oder Spritzauftrag. Die Auftragsmenge wird so gewählt, daß die angebotene Menge an Fluor des Wirkstoffs (erfindungsgemäße Verbindung) für das Leder und Pelzmaterial 0,05 bis 1,5 Gew.-% beträgt, vorzugsweise 0,1 bis 1 Gew.-%, Gewichtsprozente bezogen auf das zu behandelnde Leder- und Pelzmaterial. Nach der Behandlung mit der erfindungsgemäßen wäßrigen Dispersion kann das Leder- und Pelzmaterial getrocknet und wie üblich fertiggestellt werden. Die Behandlung mit der erfindungsgemäßen wäßrigen Dispersion beeinträchtigt weder die Farbe noch den Griff der behandelten Leder und Pelze, noch wird das freie Spiel der Wolle und Haare von Pelzen durch Verklebung derselben beeinträchtigt.The treatment of the leather and furs with the aqueous dispersions according to the invention is carried out by the customary methods, for example in the bath, by dipping, brushing or spraying. The application amount is selected so that the amount of fluorine offered for the active ingredient (compound according to the invention) for the leather and fur material is 0.05 to 1.5% by weight, preferably 0.1 to 1% by weight, based on percentages by weight the leather and fur material to be treated. After treatment with the aqueous dispersion according to the invention, the leather and fur material can be dried and finished as usual. The treatment with the aqueous dispersion according to the invention does not impair the color or the feel of the treated leather and furs, nor does the free play of the wool and hair of furs be impaired by adhesive bonding thereof.
Die Erfindung wird nun an Beispielen noch näher erläutert.The invention will now be explained in more detail using examples.

In diese Mischung mit Raumtemperatur wurde unter der starken Scherwirkung einer Dispergiermaschine vom Typ Ultraturrax eine80 °C heiße Lösung von 1,74 kg Wirksubstanz (Komponente A) in 0,2 kg Polyoxethylensorbitanmonooleat mit 20 Oxethylen-Einheiten (Komponente C), 1,0 kg Adipinsäuredibutylester und 0,5 kg Butylacetat (Komponente D) und 0,5 kg Diethylenglykoldimethylether (Komponente E) eingerührt, wobei die Temperatur in der Vorlage auf 35 °C anstieg. Die grobe Dispersion wurde ca. 30 min mit dem Ultraturrax weiterbehandelt, wobei die Temperatur auf 40 bis 45 °C anstieg. Hierbei entstand bereits eine äußerlich ansprechende Emulsion, die aber in dieser Form noch nicht lagerbeständig ist, sondern sich bald absetzen würde. Die erhaltene Rohdispersion wurde nun einer abschließenden Feindispergierung unterworfen, und zwar durch Beschallung mittels einer Ultraschallmaschine (z. B. vom Typ Sonifier der Fa. Branson), bis mindestens 90 % der Teilchen eine mittlere Größe von 1 um erreicht oder unterschritten hatten.Um den besten Wirkungsgrad der Ultraschallmaschine und eine optimale Beschallung zu erreichen, pumpt man am besten die Rohdispersion durch die auf 40 °C temperierte Schallkammer (die Temperierung der Schallkammer wird mit Hilfe eines durch einen Thermostaten regulierten Wasserbades erreicht), bis die erforderliche Feinverteilung vorliegt, wozu gegebenenfalls noch ein zweiter und dritter Durchgang erforderlich ist; Durchlaufgeschwindigkeit 10 l/h.

A 80 ° C solution of 1.74 kg of active substance (component A) in 0.2 kg of polyoxethylene sorbitan monooleate with 20 oxyethylene units (component C), 1.0 kg, was introduced into this mixture at room temperature under the strong shearing action of an Ultraturrax dispersing machine Adipic acid dibutyl ester and 0.5 kg of butyl acetate (component D) and 0.5 kg of diethylene glycol dimethyl ether (component E) were stirred in, the temperature in the receiver rising to 35 ° C. The coarse dispersion was further treated with the Ultraturrax for approx. 30 min, the temperature rising to 40 to 45 ° C. This already gave rise to an externally appealing emulsion, which is not yet stable in this form, but would soon settle. The raw dispersion obtained was then subjected to a final fine dispersion, namely by sonication using an ultrasound machine (e.g. of the Branson Sonifier type) until at least 90% of the particles had reached or fallen below an average size of 1 μm To achieve the best efficiency of the ultrasound machine and optimal sound, the best way to pump the raw dispersion is through the sound chamber, which is heated to 40 ° C (the temperature of the sound chamber is achieved with the help of a water bath regulated by a thermostat), until the necessary fine distribution is achieved, which may be the case a second and third pass is required; Throughput speed 10 l / h.
Man erhält 10 kg einer sehr feinen milchig opaken Dispersion mit einem Gehalt an wirksamem Fluor von 8 Gew.-% (berechnet aus der Menge an Wirksubstanz in der Dispersion), die auch bei -20 °C und +40 °C noch einwandfrei lagerstabil ist.10 kg of a very fine, milky, opaque dispersion having an active fluorine content of 8% by weight are obtained.
